Use a handy vacuum pump to check.

Replace vacuum hose with the check valve as a set if damage or
deformation is present at the vacuum hose.

When connected to booster side (1):

 Vacuum decrease should be within 1.3 kPa 
(10 mmHg, 0.39 inHg) for 15 seconds under 
a vacuum of  –66.7 kPa (–500 mmHg, –19.69 
inHg)

When connected to engine side (2):

 No vacuum will be applied

CAUTION:

• Clean dust on caliper and brake pad with a vacuum dust collector. Do not blow with compressed air.
• While removing brake pad or cylinder body, do not depress brake pedal because piston will pop out.
• It is not necessary to remove torque member mounting bolts and brake hose except for disassembly

or replacement of caliper assembly. In this case, hang cylinder body with a wire so that brake hose is
not under tension.

• Do not damage piston boot.
• If any shim is subject to serious corrosion, replace it with a new one.
• Keep rotor free from brake fluid.
• When replacing brake pad, replace shim with a new one.

2.

Remove sliding pin bolt (lower side).

3.

Hang cylinder body with a wire, and remove pads, shims and
pad retainers from torque member.

CAUTION:

When removing pad retainer from torque member, lift pad
retainer in the direction shown by arrow, so as not to
deform it.

INSTALLATION 

1.

Apply M-77 grease or equivalent to the shims. Install shims to pads.

CAUTION:

Securely install shims according to mounting direction of pads.

2.

Apply M7439 grease or equivalent to pad contact surface on pad retainers. Install pad retainers and pads
to the torque member.

CAUTION:

• When installing pad retainer, attach it firmly so that it is

not lifted up from torque member, as shown.

3.

Install cylinder body to torque member.
NOTE:
Use a disc brake piston tool (commercial service tool) to easily press to piston in.

CAUTION:

Check the brake fluid level in the reservoir tank for fluid level because brake fluid returns to mas-
ter cylinder reservoir tank when pressing piston in.

4.

Install lower sliding pin bolt (lower side), and tighten it to the specified torque. Refer to 

BR-24, "Compo-

nent"

  .

5.

Check brake for drag.

6.

Install tires to the vehicle.

and remove caliper assembly from vehicle.

INSTALLATION 

1.

Install caliper assembly to vehicle, and tighten mounting bolts to the specified torque. Refer to 

BR-24,

"Component"

  .

CAUTION:

Before installing torque member to vehicle, wipe oil and grease on mounting surface of steering
knuckle and torque member.

2.

Install brake hose to caliper assembly. Refer to 

BR-14, "Hydraulic Circuit"

 .

3.

Refill with new brake fluid and bleed air. Refer to 

BR-8, "Bleeding Brake System"

  .

Brake Burnishing

INFOID:0000000001717009

Burnish the new braking surfaces according to following procedure after refinishing or replacing disc rotors,
pads, or if a soft pedal occurs at very low mileage.

CAUTION:

• Be careful of vehicle speed because brake does not operate easily until pad and disc rotor are

securely fitted.

• Only perform this procedure under safe road and traffic conditions. Use extreme caution.

1.

Drive vehicle on straight, flat road.

2.

Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.

3.

Drive without depressing brake pedal for a few minutes to cool brake.

4.

Repeat steps 1 to 3 until pad and disc rotor are securely fitted.
